Abstract: This method relates to the manufacturing a hot-formed, heat treatable aluminum base alloy rod(17) containing 0.5 - 0.9 wt. % Si, 0.6 - 0.9 wt. % Mg and the remainder essentially aluminum, cooling a cast metal during casting at a rate to which no solidification shrinkage occurs. The alloy metals will precipitate to the grain boundaries of the aluminum base metal. No substantial immediate precipitation occurs within an interval before any substantial precipitation occurs.

Abstract: A method of continuously manufacturing a hot-formed heat-treatable aluminum base alloy product having a substantially extended shelf life comprises casting a molten aluminum base alloy metal, cooling the cast metal during casting at a rate at which inverse segregation will be substantially minimized, raising the temperature of the cast metal, prior to the initiation of the hot forming, to a temperature above the temperature at which the alloy metals will precipitate substantially, subsequently reducing the metal temperature from the solutionizing temperature of the metal to a temperature at which no substantial immediate precipitation occurs, within a time interval short enough to prevent any substantial precipitation, and so controlling the solution heat treatment time and temperature that the hot-formed product has controlled precipitation during natural aging.

Abstract: Disclosed in the appended specification and claims are a heat resistant aluminum alloy having a minimum conductivity of 61 percent IACS and high elongation, tensile strength and yield strength consisting of from about 0.04 to about 0.85 weight percent silicon, from about 0.30 to about 0.95 weight percent iron and from about 98.20 to about 99.66 weight percent aluminum and a method for producing said alloy comprising the steps of alloying the recited elements, continuously casting the alloy into a bar, hot-rolling the bar substantially as cast into a continuous rod, cold-drawing the continuous rod into a wire without intermediate anneals and annealing or partially annealing the wire.
